Drink with blooming tramp! (4-3-3)
I believe the answer is:
down-and-out
'tramp' is the definition.
(thesaurus)
'drink with blooming' is the subsidiary indication.
'drink' becomes 'down' (downing is a kind of drinking**).
'with' becomes 'and'.
'blooming' becomes 'out' (I've seen this in other clues).
'down'+'and'+'out'='downandout'
(Other definitions for down-and-out that I've seen before include "Impoverished - destitute person" , "Impoverished (and unconscious?)" .)
